It would also be good to re-derive our results in other methods, e.g. using the Fujikawa procedure of path integrals. These methods would all need to be re-examined however as we have an underlying degenerate metric structure and a non-Riemmannian manifold where these field theories live. We are also interested in a holographic check of our anomaly using methods similar to [1]}, now for 3d asymptotically flat spacetimes. Some of the above are works in progress.
